What I'm looking for

I'm looking for opportunities that challenge my frontend development skills and allow for collaboration in product design.

I'm a frontend-focused Software Engineer with nearly a decade of experience designing and building intuitive, scalable, and JSON performant web applications. My career has spanned enterprise SaaS, insurance tech, and digital transformation initiatives—where I’ve consistently combined technical depth with a strong eye for UI/UX.

At Omnipresent, I led the creation of a company-wide Design System and implemented a robust, reusable UI component library using React, TypeScript, and Storybook. Working closely with product designers, I helped turn ideas into maintainable, user-friendly solutions, always backed by comprehensive test coverage and frontend best practices.

I'm passionate about the intersection of usability and engineering—building not just what works, but what delights. I'm currently open to opportunities that allow me to push the boundaries of frontend development and product design.
